Creating Proportional Venn Diagrams Using Google and SAS ® Hillary Kruger, RTI International, USA
(1) What are Venn diagrams? (2) Why use them? (3) What are good and bad examples? (4) How are they made in SAS ® with Google? (5) Resources and References Proportional Venn Diagrams
What is a Venn Diagram?
Why Choose a Venn Diagram? + Venn diagrams are an effective and efficient way to show overlapping data + Easy to understand for a variety of audiences + Universally useful across disciplines + Recent resurgence in popularity
Venn Diagrams Some Venn diagrams are not mathematically accurate, but are still useful - or at least entertaining
Venn Diagrams To accurately reflect data sets, one must create diagrams that show the true overlap in data
Venn Diagrams in SAS ® SAS ® offers Venn options (like below) but they are not proportional
Proportional Venn Diagrams in SAS ® Others have addressed this previously, using tedious code, and produced the following results:
Proportional Venn Diagrams RECAP: current options BETTER: Not visually interesting FAIR: Interesting; not mathematical GOOD: Not visually accurate
BEST: Visually interesting and mathematically accurate; simple implementation Proportional Venn Diagrams New Option: Google and SAS ®
Pros and Cons SAS ® Only PROS: Mathematically accurate CONS: Visually uninteresting; tedious code SAS ® and Google Pros: Mathematically accurate; plethora of visualization options; simple application Cons: ??
A Simple Venn Diagram Using Google Here are the basic components for Google chart calls: cht= & chd= & chs= &...additional_parameters... cht = v & chd= t : 50,60,0,20,0,0,0 & chs= 300x225 & chco= FF6342,ADDE63 &
